IMPROVEMENT IN OILERS FOR CRANK-WRISTS.

Specification forming part of Letters Patent 0. 168, 163, dated September 28, 1875; application filed August 28, 1875. a

To all whom it may concern:

Be it known that I, CHARLES KURTH, of Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and the following is a specification:

In the accompanying drawing, Figure 1 rep- Improved Oiler for Crank-Wrists, of which resents a top view, and Fig. 2 a vertical central section, of my improved oiler for cranlc wrists, on the line 00 at, Fig. 1.

Similar letters of reference indicatecorresponding parts. a

Theobject of my invention is to provide an revolving journaled pipe, with the perforated crank-pin, for conveying a certain quantity of oil at each revolution of the shaft.

In the drawing, A represents the oil-receptacle, with regulating stop-cock, which is attached to a bed-plate, B, and connected, by a bottom aperture and exit-channel, a, with the I crank-pin connecting-pipe O, that is secured at one end by a screw-journal, b, into the bed- The connecting-pipe (J is bent at each end, but in opposite direction at right angles, and the other end set into a central perforation, d, of the crank-pin D. A certain play in lateral direction is given to pipe 0 to allow for small inaccuracies of the revolving parts.

The perforations d of the crank-pin D are eX- tended at right angles to the longitudinal entrance part, into which the oil-pipe O enters, so as to supply the oil to the crank-wrist.

A small quantity of oil is conducted from the oil-receptacle to the wrist when the crankpin and oil-pipe pass through the lower half of each revolution, furnishing thus an even and continuous supply to the crank-Wrist without interrupting the running of the engine.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Theoombination of oiler A, bed-plate B, having channel a, the journal I), the bent pipe 0, the Wrist-pin having angle-hole d, as and. for the purpose specified.

CHARLES KURTH.
